We can't answer for a couple of reasons. Winchester does not make 44 pistols. Any load data is based on exact caliber (there is more than one 44 caliber) the bullet weight and type, and the type of powder used (there are dozens of different powders)
1 pound = 7 000 grain
depends on which powder, and which .44. There were several different catridges with 44 in the name.

Nothing, really, but the name of the cartridge. When Winchester introduced the Model 94 in 1894 in the brand new smokeless powder round .30 Winchester caliber, most of the other ammunition on the market was black powder and had names such as 25-20, 44-40, 45-70, etc. These names stood for the caliber (diameter of the bullet) and how many grains of black powder were in the load. The .30 Winchester didn't follow that convention an dpeople didn't know what to expect, so it was not well accepted in the market and sold poorly. In a marketing move, Winchester changed the name to 30-30 (still, of course, a smokeless powder round with identical components as the .30 Winchester) and the guns and ammunition sold quite well.
It depends greatly on the weight of the projectile, and the exact type of powder used. Though in general, the grain weight of a 5.56 powder charge is between 20 and 26 grains. Much more than that won't fit in the case.
Yes. The gas ports on the 1400 barrel will fill up with dirt/powder residue but it will work fine. I have been using an cut down 1400 barrel on my 1300 for many years.
There have been many over the years most were "store brands" during the 70's black powder shooting surge with the exception of Ultra-Hi and Miroku they were sold in the US under there respective names.
Actually, the powder is in the cartridge case. A bullet is the metal projectile that is fired out of the barrel. The powder for a 9mm Parabellum (also called 9mm Luger) cartridge will be one of several different smokless powders. I use Bullseye or Unique for many of my pistol loads, but there are dozens that can be used.
Yes. Many other early developed cartridges bore the wcf label as well. Like the .22 hornet, 30-30,and pistol cartridges as well.
Powder charges are traditionally weighed in GRAINS rather than grams. Originally, the .22 LR was loaded with 7 grains of very fine black powder. All present day 22 LR ammo is loaded with smokeless powder, and the charge is about 1 grain.
No one answer. That depends on the load and the powder used. Please understand that as used in that sentence, grain refers to a unit of weight, and not the individual grains of powder. Typical charge weights can vary from 17-35 grains.
